The sedan version of Honda’s new Honda Civic Type R will go on sale in Japan beginning today, Friday March 30th 2007. Key features include the high performance high revving K20A 2.0 liter normally aspirated engine found in the Europrean Civic Type R hatch mated to a 6-speed manual transmission, a torque-sensitive helical LSD, large 18 inch wheels providing a peek at the huge 17 inch disc brakes with 4-pot Brembo calipers behind them, as well as a sporty bodykit. The bodykit includes a new bonnet design with a more prominent dome. Suspension has also been tuned for sporty performance and features thicker stabilizer bars.

Interior enhancements over the normal sedan include a new black color scheme, bucket seats exclusively designed for the Civic Type R Sedan, a new dash featuring i-VTEC engine revolution indicator alerts, a small-diameter leather-wrapped oval steering wheel, an aluminum ball-type shift knob, a short stroke sports shift linkage, metal sports-type pedals and footrest, and a button-type engine starter.

In this edition, the K20A revs all the way up to 8,000rpm with an output of 225 PS, and churns out a peak of 215Nm of torque at 6,100rpm. Throttle activation is via drive-by-wire, and the intake and exhaust manifolds are tuned for high revolution engine output. The 6-speed gearbox ratios are perfectly matched to the rev range and torque curve, as can be seen from the gear position, revolution and torque curve chart after the jump. It also sports a highly rigid aluminum transmission case and a baffle plate to mitigate oil starvation during high speed cornering.
